Bug 1348173 - stylo: combined gecko side patch for -moz-border-*-colors support. 1. add binding functions for -moz-border-*-colors support. In Gecko, we use double pointers to nsBorderColors to store -moz-border-*-colors. The computed values of -moz-border-*-colors are set by couple member functions. To pass the computed value from Servo to Gecko, we need support for these member functions as well. So, I'm adding some binding functions in this patch. The actual use of these bindings to pass/store the computed values is separated in the following patch, which should be a pure Servo change. See servo PR: https://github.com/servo/servo/pull/16586. 2. update test expectations for -moz-border-*-colors support. Note that with the support of -moz-border-*-colors, 165 mochitests and 17 reftests could be fixed. MozReview-Commit-ID: KDbp8C6Aoqd

Bug 1015466 - Part 3, implement OnStartRequest/OnStopRequest/OnTransportAndData/OnProgress/OnStatus/OnRedirect3Complete/OnDiversion on background channel. r=mayhemer MozReview-Commit-ID: FymUsRom8eq

Bug 1015466 - Part 2, PHttpBackgroundChannel lifecycle management. r=mayhemer PHttpBackgroundChannel is created by content process because PBackground IPDL can only be initiated from content process. The background channel deletion is controlled by chrome process while PHttpChannel is going to be closed or canceled. BackgroundChannelRegistrar is introduced for pairing HttpChannelParent and HttpBackgroundChannelParent since they are created over different IPDL asynchronously. nsIParentRedirectingChannel.continueVerification is introduced to asynchronously wait for background channel to be established on the new channel during the Redirect2Verify phase.

Bug 1015466 - Part 1, skeleton of PHttpBackgroundChannel. r=mayhemer PHttpBackgroundChannel is introduced to deliver OnStartRequest/OnStopRequest/OnTransportAndData/OnProgress/OnStatus on background thread. Redirect3Complete is moved to PHttpBackgroundChannel to ensure redirect procedure in completed before any channel event is handled. FlushedForDiversion/DivertMessages is moved to PHttpBackgroundChannel to ensure no more channel event are delivered after these two messages on the background channel.

Bug 1357878 - Maximize window synchronously and restore when maximized; r?maja_zf When refactoring the tests for the Set Window Rect command, it was discovered that the Maximize Window command was not synchronous. This patch makes GeckoDriver#maximizeWindow synchronous by waiting for the DOM resize event to fire before returning the window rect to the user. It also aligns the command with the WebDriver standard by making it restore the window to its original size when calling the command a second time. MozReview-Commit-ID: Ft3tn2A4m7u

Bug 1357878 - Prevent hang on setting window size to existing size; r?maja_zf When the window's size is being set to the window's existing size, Marionette unconditionally listens for the DOM resize event. When a window is not resized, no such event fires. This patch skips setting the window size when the window's current size is the requested size. This bypasses the problem of listening for an event that never occurs. It also combines the window position- and size tests into a test_window_rect.py test, since they share many of the same characteristics.

Bug 1354679 - Show the paused debugger overlay when script gets paused; r=ochameau A previous bug had introduced a new overlay (highlighter) that was aimed at being shown when the debugger would pause. This commit adds the necessary code to the ThreadActor for the overlay to be shown when script execution is paused, and hidden when script execution resumes. This commit also adds a test to cover this feature. MozReview-Commit-ID: 3LT5MbJgbYq
